4To all whom it may concern.'

Be it known that I, RALPH A. SCHOEN- BERG, of New York, in the county ofNew York and State of New York, have invented new and useful Means forOperating Switch Mechanisms, of which the followingrv is aspeciicatioin-this application being` adivisonof my application filedFebruary 9, 1914, Serial No. 817,472. y

My. invention relates to means for operating switch mechanisms andparticularly when such mechanisms are placed in sockets, or otherreceptacles., especially when adapted for carrying electric light lampsor attachment plugs.

In the case of sockets or other receptacles it is highly desirable to doaway with the unsightliness caused lby protruding actuators, such askeys, chains and push-buttons. These actuators are a distinct drawbackas a matter of appearance and particularly in the case of very finefixtures and require not Vonly perforation of the socket or otherreceptacle but also perforation of the. husk or socket cover when thelatter is used as4 well as alinement of the perforations of socket andhusk. 1-

One object of my invention is to do away with such protruding actuatorsand my invention consists partly in providing a support for anelectrical appliance such, for. example, as a lamp or attachment plug,movable longitudinally in one direction to make the circuit and alsomovable in thesame direction vto break the circuit.

A" feature consists 'in a 'support normally occupying its inner positionbut movable outwardly in' preparation. for active. opera# tion and then'movable inwardly" tofgchange the condition ofy 'the circuit.

Another feature 4'( onsist's 'infav SteP-.by-step' operating mechanism.'u Another feature consists in the mounting.' of'the several parts onrelatively movable insulating members. i. Other features will be pointedout below.'

vice used as a'lamp socket and provided with a cord attachment throughwhich the lamp is manipulated to operate the switch.

Reference characterl-indicates the stationary porcelain block, 2 themovable porcelain block, 3 the screw shell, f1 the lining of insulatingmaterial inclosing said parts, 5 the metal shell surrounding the lining4, 6 the cap of shell 5 and 7 and 8' the lead wires. ','The stationaryporcelain block 1 is made with a recess 9 within lwhich is' arrangedl yalratchetwheel 10 provided upon one face with a series of studs 11coperatingwith a spring pawl 12 fastened by a screw 13 to tlie movableporcelain block 2. The' porcelain block2 normally occupies its innerposition abut' is moved outwardly by handl in preparation for activeoperation and is then released *and moves inwardly to make .or break4the circuit and the spring pawl 12 movingwith it acts to rotate ratchetvwheel `10 step by step. The ratchet wheel 10 is made with fourlaterally projecting lugs .14 adapted by the rotation of said wheel tobe brought successively. into engagement with a stationary contact 15fastenedy by a screw 16 to the stationary porcelainblock l. The contact15 is-made with a downwardly extending finger 17 which is in permanentengagement with a contact linger 18 riveted or otherwise secured to thescrew'shell` 3. l A springfdetent 19 bears against ratchet wheel ,10,and cooperates with ythe studs 11 to'preventxreverse movement of ysaidratchet' lwheel on the down strokesof pawl'12. Thisy detent 19 isfastened. to;the.stationary,porcelain block- 2 by meansof a screw2 0which serves also as a binding-post with which ,the 'line wire 7 isconnected, Detent. y19: .notf'only prevents re'- verse-inoveinent fof,ratche-t wheel 1'0 `1butr also,

rseryesagsgnin,electric connection between binding postjscrew. 20* andsaid ratchet" wheel.,;.r"l`he studs `11 are provided andarranged`soj'thatf each 'upward movement ofA p'awl 12 rotatesl ratchet wheel1Q-a distance equal to` the angulardistanceibetween' -tvvf ofthe `studsso that every` other upstioke'A of pawl 12jshifts one ofthe lugs '14into engagement with contact 15 while the'alteiu` ter contact 21 ismadewith a threaded'hole to receive the lower threaded extremity of apost 22 provided at its upper end with a head 23 beneath v,which isarranged a springl 24, said spring serving to normally hold the block 2against the porcelain block 1.

n its under side the porcelain block 1 is made with a recess 25 withinvwhich is arranged a contact 26 that is fastened to. the porcelainblock'l by means of a screw 27. The screw l27 serves as a binding postto which the other line wire 8 is connected, and the contact 26 isin-permanent engagement with a stationary contact 28 provided onthecenter contact 21. The screw shell 3 and porcelain block 2 aremovedbodily to open and close the circuit at 19-15 and when thus movedthe contacts 28 and 18 slide upon f the contacts 17 and 25 withoutleaving the latter.' In Fig. 1 I have shown a connecting plug 29 mountedwithin the screw shell 3 and at 30 and 31 are the line wires leadingfrom this connecting plug to the heater or other instrument. When thecircuit through the heater or other instrumentI connected with the wires30 and 31 is open and it is\ desired to close the same the operatormayaccomplish this merely by pulling upon said wires and then releasingthem. The pull upon the wires draws the connecting plug 29, screw shell3, porcelain block 2 and post 22 outwardly-against the pressureof spring24 which latter returns said parts to' their innermost positions whenthe pull upon wires 30 and 31 is relaxed. Pawl 12 moves with theporcelain block 2 and through its engagement with the ratchet wheel 10turns the latter one step carrying one of the lugs 14 into engagementwith the contact 15 thereby closing the circuit through the heater orother instrument. Whenit is desired to open the circuit through theheater or other instrument the operator will again pull upon the wires30 and 31 which results in another in and out movement of the connectingplug 29 and parts connected therewith. When block 2 is thus moved withthe connecting plug29 its pawl 12 again-moves ratchet wheel 10 one stepcarrying the lug 14 resting against contact 15 away from and out ofengagement with the latter thus opening the circuit through the heateror other instrument. It will thus be seen that with this orm ofmyinvention an important advantage resides in the construction whichpermits of its being operated from a distant point to open and close thecircuit through the mediumy of the wires 3Q and 31.

My improved switch device may b ey used to hold a lamp as shown in Fig.6 and if it y is to be placed in an elevated position where it cannot beconveniently reached yI may provide an attachment 32 shown in Fig. 6consisting of an annular flexible strap 33 whose ends are fastenedtogether by means of a screw 34 so that the strap is confined betweentwo shoulders 35 and 36 thatare provided upon the exterior of shell 5.`This strap 33 'ismade with .a depending arm 37 extending downwardlyalongside. kof the lamp bulb 38 and at the lower. end of this arm thereis provided a bell-shaped cord guiding aperture 39. One end oi' a cord40 is tied around the shank vof the bulb 38 and said cord extendstherefrom downwardly through the guide 39 with'its lower end arranged inaconvenient position.

The stationary porcelain block 1 of Fig. 1 is made at its lower end withtwo diametrically opposite lugs 4:1occupying two notches 42 provided inthe -movable porcelain block 2.- These lugs and sockets connect thetwo'porcelain blocks so that they can be moved relatively toward andfrom each other but are held against relative rotative movement.
